Effect of Rearing at Different Densities and Dietary Supplementation with Vitamin E on Growth Indices, Survival and Carcass Composition in Fingerling Rainbow Trout (Oncorhynchus mykiss)
This study was conducted to investigate the effect of rearing at differing densities and dietary supplementation with vitamin E on growth indices, survival and carcass composition in fingerling rainbow trout in a 6-week trial. Rainbow trout juveniles with initial body weight of 9.6 ± 0. 69 g at two densities of 50 and 100 pieces per 50 liter were fed two diets with the same protein and fat cont...

A 10-week feeding experiment was conducted to evaluate the effects of feeding level, energy and protein maintenance requirement of rainbow trout, Oncorhynchus mykiss, fingerling (5.65±0.45cm; 1.42 ±0.25g) by feeding casein-gelatin based purified diet (45% CP; 3.67 kcal g-1 GE) at six feeding levels 2-7% of BW/day in two equal meals, at 0800 and 1700 h, in triplicate, with 20 fish per trough fi...
متن کاملEffects of different feed restriction periods on the growth and fatty acid compositions in juvenile rainbow trout (Oncorhynchus mykiss)
The aim of this study was to determine the effect of different feed restriction periods on the growth performance as well as the biochemical and fatty acid compositions of fillet in rainbow trout (Oncorhynchus mykiss). Fish with an average initial weight of 64.80±7.41g were used in the study. The trial lasted 60 days and 4 different feeding diets were alternately applied to the fish. The contro...
